Since the object is larger, the dilation can not be negative and less than 1. Therefore, your answer is 1.25 (d). Also, 4 * 1.25 is 5.
Hello again,
"katie deleted your answer to the question Hello,a=2, b=8, c=-1Indeed,y=f(x)=ax...
You've been warned"
Answer is a=2, b=8 and c=-1
Indeed:
y=f(x)=ax²+bx+c
Since (-2,-9) is the vertex,
y=k*(x+2)²-9
Or f(-1)=-7 ==> -7=k*(-1+2)²-9 ==> k=2
f(x)=2(x+2)²-9=2*(x²+4x+4)-9=2x²+8x+8-9
<u>f(x)=2x²+8x-1</u>
A proof: the picture is following.
Answer:
20 gallons
Step-by-step explanation:
Divide 120 miles by 8 to find miles per gallon
120 ÷ 8 = 15 miles per gallon
Now divide 300 miles by 15 to find number of gallons required
300 ÷ 15 = 20
20 gallons are required for a journey of 300 miles
